    QUE94269 sample

Macroscopic Description: Roberta Score
This lunar meteorite is identical to QUE93069 and would probably fit together if QUE93069 was still in one piece. One side of this flat stone has thick gray-green, frothy fusion crust. The other side has thin, weathered, dull green-brown fusion crust. A fractured surface reveals the interior matrix which is dark gray to black with abundant inclusions. The largest inclusion is white and measures 1.0 x 0.2 cm. The newly exposed interior surface has a lighter gray-colored matrix and abundant white and gray clasts. One white clast measures 0.4 x 0.2 cm. Other inclusions present include fine-grained, buff-colored clasts, several brecciated gray clasts, and smaller white clasts. Many clasts have weathered to a yellowish color. As in QUE93069, most of the clasts are small and friable and, unfortunately, are not extractable.

Thin Section (,5 and ,7) Description: Brian Mason
The sections show a microbreccia of granular clasts, up to 1.5 mm across, and small plagioclase grains, in a translucent to semi-opaque brown glassy matrix; one grain of metallic iron, 0.3 mm across, was noted. Most of the plagioclase is almost pure anorthite (Na2O 0.3-0.5%, K2O less than 0.1%), with a few grains with higher Na2O, up to 3.2%. QUE94269,7 has a 3 mm clast of subequal amounts of plagioclase and pyroxene; the plagioclase is anorthite (Na2O 0.3-0.5%), the pyroxene ranges from Wo5Fs39 to Wo34Fs22 with fairly uniform En content. This specimen is a lunar meteorite, very similar to QUE93069 (Antarctic Meteorite Newsletter 17(2), 1994), with which it is certainly paired.
